WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No, 367,168, dated July 26,1887.

Application filed April 14, 18$]. Serial No. 934,824. (No model.)

To all whom it may concern:

Be it known that I, THOMAS J. TIMMONS, a citizen of the United States,residing at Godwin, in the county of Maury and State of Tennessee, haveinvented certain new and useful Improvements in WVagon-Brakes; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and i to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention has relation to improvements in wagonbrakes; and itconsists in the novel construction and arrangement of its parts, ashereinafter fully described in the specification, and set out in theclaims.

In the accompanying/drawings, Figure 1 is a sectional view of Fig. 2,cut through on the line a; :0. Fig. 2 is a top plan view of myinvention.

My invention is described as follows:

My invention can be applied to any of the wagons now in use, or,by-little change of mechanism, may be applied to vehicles having shafts.

In the accompanyingdrawings, a represents the tongue of the wagon. arepresents the nose of the tongue. In the nose is journaledperpendicularly a wheel, a Underneath the said tongue a light rod, 1),is secured, which works through a number of staples, b, to hold it inplace. To the front end of the said rod is secured a large ring, b toprevent the rod from being drawn through the nose of the tongue, to theend that should any accident happen to break it loose from its fasteningat its rear end the horses would still be secured to the end of thetongue by the tongue-chains. To this large ring b is secured a shortchain, b which passes around the wheel aand up through the nose of thetongue. To the outer end of this chain is attached the tongue-chains. Alittle beyond the rear end of the tongue a, and between the hounds c, isjournaled a wheel, 0, and to the rear end of the rod b is attached achain, c,which passes around the said wheel 0', and has its upper endsecurely fastened to the strap 6 which is secured to the upper face ofthe doubletree 0 This chain is secured to the wheel 0 by a staple, c",or other suitable means. Secured to the said wheel 0', a short distancefrom its center, are two rods, 0 one on either side, which are pivotedin place by any suit-able and substantial means. These rods extend backand are passed through the brake-bar d, and there are on each rod twonutsone against the front and the other against the rear faceso that thebrake-bar can be adjusted as circumstances may require. The saidbrake-bar d is swung on the lower part of the houndsin loops, while theslider is secured on the top of the hounds. I can, if I see proper, andclaim the right to, dispense with the slider and secure the saidbrake-bar on top of the said hounds, in which event it would answer asthe slider.

The doubletree c occupies its usual posi-.

tion on the front end of the hounds and the rear end ofthe tongue; butit is not secured by V a bolt,- as is usual, but by two bands or loops,

as follows:

Loop 0 has its rear end secured to the rear end of the tongue at andrises perpendicularly the thickness of the doubletree, or a little more,and then extends forward beyond the front edge of the doubletree and thespring 6, and then down, and then forward, and is secured to the tongue.however, to allow the doubletree to play back and forward, the purposeof which is hereinafter explained. A strap, c", passes over the saidstrap 6 and has its ends secured to the said doubletree. Thisarrangement keeps the doubletree from moving endwise in eitherdirection, but allows it to move backward and forward, as above shown.To the front face of the doubletree is secured the spring 6', whichworks against the front part of the strap e, the purpose of which ishereinafter explained. This spring may be a leaf-spring, as shown in thedrawings, or I may use a spiral or rubber spring. The stay-chains f f,which are secured to the axle,have their front ends attached to theextreme ends of the doubletree beyond the hooks f, to which the horsesare attached. To the rear face of the doubletree is hinged the two rearends of the lock 9, one on either side of the strap 6. This lock is soshaped that it lies over the upper face of the doubletree and over thestrap 6 close down and fitting to the same, its front end, 9, beingturned down Its loop islong enough,

and fits snugly against the front face of the strap 0, the purpose ofwhich is hereinafter explained.

Myinvention operates as follows: \Yhen the wagon starts down an incline,the wheelhorscs pull back on the tongue-chains, which operation drawsthe rod 1) forward. This rod, operating on the chain 0, turns the wheel0' backward. This in turn draws the rod 0 forward,which brings thebrake-bar (1 against the rear face of the front wheels and brakes thewagon. \Vhen the horses pull on the tongue chains, as above described,the doubletree is thereby left free and may be moved back. As soon as itis thus left loose, the spring 0 starts it back, and, pulling on the rod1), actuates the chain a as before described, which draws the doubletreefarther back. As soon as the wagon reaches the plane again, the horsesthrow the doubletree forward, which turns the wheel 0 forward. Thisaction releases the brake d. The above operations are auton1aticallyperformed as often as the wagon descends an incline and strikes theplane or runs over a bowlder or other-like thing. Every time the horsespull on the tongue-chains they will put on the brakes, and every timethey pull on the doubletree they take off the brakes.

Lock 9, above described, is not usually worn over the doubletrec, butlies back on the chain, and is used for the following purpose.

\Vhen I wish to back the wagon, l throw the lock forward, an 1 its frontend, r/, fits down closely against the front part of the strap (2 andlocks the doubletrec, so that when the horses pull on the tongue-chainsthe brakes will not move, and consequently the wheels will not belocked. The object in having the stayehainsf attached to the rear end ofthe doubletree 0 and beyond the point 1'" to which the horses areattached is to the end that in turning the wagon-we will say to theleft, for instancean inexperienced driver might permit the saddle-animalto pull on its tongue-chain, and this would have a slight tendency,though the pull would be at a very considerable angle, to put on thebrakes. To avoid this, the righthand-wheel mule, being attached to thedoubletree at the point f, would counteract such tendency and keep thedoublctree from sliding back, and consequently prevent the brakes frombeing put on. As an additional precaution, I also attach a chain, f, tothe doubletree at the point f", and to the inner end of thesingletreesj", and thus keeping the doubletree and singletree onparallel lines. I

do not confine myself to the chain; but may use any equivalent means.

Having described my invention, whatI claim as new, and desire to secureby Letters Patent, is

1. The combination, with the wagon, of the wheel a, journaled in thenose a, the chain I)", passing around said wheel and attached to thelarge ring I), ring I)", attached to the rod 1), passing along the underside of the tongue, chain 0', attached to the rear end of said rod,passing around wheel 0, and its front end attached to strap c", rods 0",their front ends pivoted to said wheel and their rear ends secured inthe brake'bar d, strap e secured to the upper face of the doubletrce a",strap 0, its rear end secured to the rear end of the tongue, said strappassing over the doubletree and under said strap 0 its front end beingsecured to .said tongue, and spring 0, working between the front face ofsaid doublctree and the front part of the loop of the strap a, substantially as shown and described, and for the purposes set forth.

2. In combination with the wagon-brake as above described, thestayehains ff secured to the outer ends of the doubletrec, the hooks f,securing the singlctree to the doubletree at a point inside of the saidstay-chains, and the chains f, one end secured to the double tree at apoint, f, near its center, and the other end to the inner end of thesiugletree, substantially as shown and described, and for the purposesset forth.

In a wagon-brake as above described, the tongue a, strap 0, securedto.said tongue, lock 9, hinged to the rear face of said doubletrec, itsfront end, y, impinging against the front part of the loop of the strap0, locking said doubletrec, substantially as shown and described.

i. The combination of the chain 1)", working around the wheel a", itsrear end attached to rod 7), rod 1), having its rear end attached tochain 0 chain 0 working around wheel 0,

, having its front end attached to the doubletrec, rods 0', attached tosaid wheel 0, and the brake-bar (I, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.
